The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

The terms “configured” and “include” used herein should not be construed as necessarily including all components or steps written in the specification, but may include only some of the components or steps or may further include additional components or steps.

While such terms as “first”, “second”, etc., may be used to describe various components, such components must not be limited to the above terms. The above terms are used only to distinguish one component from another.

The various embodiments below relate to an image forming apparatus that executes an application for performing an image forming operation, and a method of performing an image forming operation by the image forming apparatus, and a detailed description of matters well known to one of ordinary skill in the art to which the following embodiments pertain will be omitted.

FIG. 1 illustrates an image forming apparatus 100 that executes an application for performing an image forming operation, according to an embodiment of the present disclosure.

Referring to FIG. 1, as the image forming apparatus 100 is connectable to the internet and includes a high-performance user interface panel, the image forming apparatus 100 is able to perform various image forming operations and increasingly needs to drive various applications for performing the various image forming operations. For example, the image forming apparatus 100 may execute not only an application previously installed in the image forming apparatus 100 but also a web application that is usable via the internet or intranet.

For example, the image forming apparatus 100 may execute a web application via a browser included in a user interface (UI) 110 or a separate compiler.

As the image forming apparatus 100 executes various such applications, the image forming apparatus 100 may frequently transmit or receive data to or from an external device, such as a web server, or may frequently refer to data flowing between the internal modules of the image forming apparatus 100, and the size of the data may increase. Accordingly, an execution speed of an application may decrease.

Thus, the image forming apparatus 100 may provide an independent application executing method to a system of the image forming apparatus 100, thereby reducing the amount of data and the number of times the data is transmitted or received, and increasing an operation performing speed of the image forming apparatus 100.

In detail, referring to FIG. 1, the image forming apparatus 100 may include the UI 110, an interface library 112, an operation processor 120, and an operation performer 130.

The image forming apparatus 100 may include one of a printer, a scanner, a facsimile machine, and a multi-function product (MFP) having various functions, such as a print function, a scan function, a copy function, a facsimile function, an e-mail transfer function, a storage function, a character recognition function, a file transfer protocol (FTP) function, and a web browsing function. In FIG. 1, only components related to the present embodiment are described so as not to obscure the features of the present embodiment of the present disclosure. However, it will be understood by one of ordinary skill in the art that general-use hardware components other than the components illustrated in FIG. 1 may be further included and therefore, the present disclosure is not limited thereto.

The UI 110 may provide information to a user and receive an input from the user. For example, the UI 110 may include a display having a display function, such as a monitor, a touchscreen, a liquid crystal display (LCD), or a light-emitting diode (LED), and an input device having an input function, such as a touch panel, a keyboard, a mouse, or physical buttons, and may further include a processor that controls these devices.

The UI 110 may provide the user with a list of image forming operations performable by the image forming apparatus 100, and receive from the user a request to perform an image forming operation. For example, the UI 110 may provide a UI screen for receiving a user input of selecting one of the image forming operations performable by the image forming apparatus 100, such as printing, scanning, copying, faxing, e-mail transferring, storing, a FTP operation, and web browsing.

In this case, the UI 110 may provide a UI screen including the image forming operations performable by the image forming apparatus 100 via a browser by referring to the interface library 112 included in the UI 110 without directly referring to the operation performer 130.

The interface library 112 includes information about the image forming operations performable by the image forming apparatus 100, and may be written in a script language, such as a java script.

For example, the interface library 112 may include identification (ID) information of the image forming operations performable by the image forming apparatus 100, and setting information necessary for performing the image forming operations. The ID information of the image forming operations may represent the types of image forming operations, such as printing, scanning, copying, faxing, e-mail transferring, storing, character recognition, an FTP operation, and web browsing. The setting information necessary for performing the image forming operations may represent, for example, a type of printing paper, the number of printouts, and a printing method.

The interface library 112 may include information about applications executable by the image forming apparatus 100. The UI 110 may provide the user with the applications executable by the image forming apparatus 100 by referring to the interface library 112 and may receive from the user a selection of an application that is to be executed.

The UI 110 may execute the selected application by referring to the interface library 112. For example, the interface library 112 may include location information of execution data for executing an application. The UI 110 may execute the selected application by referring to the interface library 112 and may provide the user with an execution screen or the like of the selected application.

The interface library 112 may be stored in a non-volatile memory included in the image forming apparatus 100. For example, the interface library 112 may be included in a non-volatile memory, such as a read only memory (ROM) or a flash memory.

The UI 110 may receive from the user a request to perform an image forming operation via the executed application. The UI 110 may receive ID information and setting information of the image forming operation requested to be performed, and may generate the image forming operation by using the received pieces of information.

When the image forming operation is generated, the UI 110 may transmit a request to perform the generated image forming operation to the operation processor 120.

The operation processor 120 (i.e. at least one processor) performs data conversion and data distribution so that all image forming operations generated via applications executed by the image forming apparatus 100 may be performed in an appropriate order and at an appropriate speed, and may be implemented within or outside the UI 110.

The operation processor 120 may call an application programming interface (API) corresponding to an image forming operation, based on the request received from the UI 110 to perform the image forming operation. At this time, the operation processor 120 may use a representational state transfer (REST)-type API, namely, a RESTful API. The operation processor 120 may include an API library for the image forming operations performable by the operation performer 130.

For example, when the image forming operation requested to be performed is a scan operation, the operation processor 120 may call a scan API corresponding to the scan operation. The scan API may drive a scan module for performing a scan operation, which is included in the operation performer 130.

At this time, the operation processor 120 may convert a format of the received request to perform an image forming operation into a predetermined data format for calling an API corresponding to the image forming operation. For example, the predetermined data format may be JavaScript Object Notation (JSON) format, such as Number, String, Boolean, Array, Object, Symbol, null, or undefined.

In other words, with reference to FIG. 1, the operation processor 120 may analyze the received request to perform the image forming operation in order to convert the received request into a request for calling an API corresponding to the image forming operation. In addition, the operation processor 120 may receive data representing a performance result of the image forming operation from the operation performer 130 and may transmit the received data to the UI 110. At this time, the operation processor 120 may convert a format of the data representing the performance result of the image forming operation and transmit the format-changed data.

In addition, the operation processor 120 may perform a user authentication required to perform the image forming operation. For example, the operation processor 120 may receive user authentication information obtained by the UI 110 to perform the user authentication. The operation processor 120 may determine whether the received user authentication information is valid, by analyzing pre-stored user information and the received user authentication information. When it is determined that the user authentication information is not valid, the operation processor 120 may terminate connection with the UI 110 and data transmission or reception to or from the UI 110.

The operation processor 120 may manage a connection to the operation performer 130 and settings of the connection. At this time, the operation processor 120 may set a real-time bidirectional connection by using a web socket method, and thus may immediately receive information about an event generated by the operation performer 130.

The operation performer 130 may directly perform an image forming operation, and may include a plurality of operation modules that respectively perform various image forming operations. For example, the operation performer 130 may include a print module, a scan module, a copy module, a facsimile module, an e-mail transfer module, a storage module, and a character recognition module.

When the operation performer 130 receives from the operation processor 120 the request to perform an image forming operation, the operation performer 130 may perform the image forming operation. In detail, the operation performer 130 may perform the image forming operation by driving a module corresponding to the API called by the operation processor 120 from among the modules included in the operation performer 130.

For example, in response to a request from the UI 110 to perform a scan operation, the operation processor 120 may convert the request to perform the scan operation and call a scan API corresponding to the scan operation, and the operation performer 130 may perform the scan operation by driving the scan module.

FIG. 2 is a block diagram illustrating in detail an internal structure of the image forming apparatus 100 of FIG. 1, which executes an application for performing an image forming operation according to an embodiment of the present disclosure.

Referring to FIG. 2, the image forming apparatus 100 may include an application 210, a UI 220, an operation processor 230, and an operation performer 240. The application 210 may be actually executed within the UI 220 because the application 210 is a program executed within the image forming apparatus 100. In FIG. 2, only components related to the present embodiment are described so as not to obscure the features of the present embodiment of the present disclosure. However, it will be understood by one of ordinary skill in the art that general-use hardware components other than the components illustrated in FIG. 2 may be further included, and therefore the present disclosure is not limited thereto.

The UI 220 may provide a UI screen including image forming operations performable by the image forming apparatus 100 and applications executable by the image forming apparatus 100 via a browser, by referring to an interface library included in the UI 220.

The UI 220 may include an interface library written in a script language, such as a java script, and the interface library may include information about an image forming operation, such as operations, devices, and image forming apparatuses (e.g., MFPs).

In detail, the operation information may include ID information of the image forming operations performable by the image forming apparatus 100, and setting information necessary for performing the image forming operations. For example, the ID information of the image forming operations may represent the types of image forming operations, such as printing, scanning, copying, faxing, e-mail transferring, storing, character recognition, an FTP operation, and web browsing. The setting information necessary for performing the image forming operations may represent, for example, the type of printing paper, the number of printouts, and a printing method.

With reference to FIGS. 1 and 2, the UI 220 is able to provide information about the image forming operations performable by the image forming apparatus 100 to a user by using operation information, without referring to an external server or the operation performer 240.

The device information may include information about devices that may be used to perform an image forming operation. For example, the device information may represent a user device (e.g., a mobile phone or a desk top computer of a user) or a web server that transmits or receives data to or from the image forming apparatus 100.

The UI 220 may provide information about devices that may be used to perform a function provided by the image forming apparatus 100 by using the device information. For example, the UI 220 may provide information about a user device capable of e-mail transferring to the user, and may receive a request to perform an e-mail transfer operation from the user.

The image forming apparatus information is about a plurality of image forming apparatuses including the image forming apparatus 100, and may include location information, performance information, and status information of the image forming apparatuses.

The UI 220 may also include information about the applications executable by the image forming apparatus 100. The UI 220 may provide the user with a UI screen including the applications executable by the image forming apparatus 100 by referring to the information about the applications and may receive from the user a selection of an application that is to be executed. The UI 220 may execute an application according to a selection of the user, by directly referring to the interface library.

In response to a request from the user to perform an image forming operation, the UI 220 may generate the image forming operation and transmit a request to perform the generated image forming operation to the operation processor 230.

The operation processor 230 may convert and distribute the received request to perform the generated image forming operation, and transmit the converted and distributed request to the operation performer 240. The operation processor 230 may transmit or receive data to or from the operation performer 240 by using a hypertext transfer protocol (HTTP) method.

In detail, the operation processor 230 including an API library for image forming operations performable by the operation performer 240 may call an API corresponding to the image forming operation requested to be performed.

The operation performer 240 may perform the image forming operation requested to be performed by driving a called module from among the plurality of operation modules included in the operation performer 240, and may return a performance result of the image forming operation to the operation processor 230.

Thus, the image forming apparatus 100 may provide an independent application executing method to a system of the image forming apparatus 100, thereby reducing the amount of data and the number of times the data is transmitted or received, and increasing an operation performing speed of the image forming apparatus 100.

FIG. 3 is a schematic diagram for explaining a method, performed by an image forming apparatus 300 according to another embodiment, of performing an image forming operation according to an embodiment of the present disclosure.

Referring to FIG. 3, the image forming apparatus 300 may include a communication interface 310 and an operation performer 320, and a device 350 includes a UI 360, an interface library 370, and an operation processor 380.

The device 350 may be used to perform an image forming operation. Examples of the device 350 may include user devices (e.g., a mobile phone, a smartphone, personal digital assistants (PDA), a portable multimedia player (PMP), a PC, or a tablet) and server devices (e.g., a web server), but embodiments are not limited thereto. Devices capable of transmitting or receiving data to or from the image forming apparatus 300 may be used as the device 350.

The user may request the image forming apparatus 300 to perform an image forming operation, via the device 350 according to an embodiment of the present disclosure.

In detail, referring to FIG. 3, the UI 360 of the device 350 may provide the user with a list of image forming operations performable by the image forming apparatus 300, and receive from the user a request to perform an image forming operation. For example, the UI 360 may provide a UI screen for receiving a user input of selecting one of the image forming operations performable by the image forming apparatus 300, such as printing, scanning, copying, faxing, e-mail transferring, storing, an FTP operation, and web browsing.

At this time, the UI 360 of the device 350 may provide a UI screen by referring to the interface library 370, without receiving the list of the image forming operations performable by the image forming apparatus 300.

The interface library 370 includes information about the image forming operations performable by the image forming apparatus 300, and may be written in a script language, such as a java script.

For example, the interface library 370 may include ID information of the image forming operations performable by the image forming apparatus 300, and setting information necessary for performing the image forming operations. The ID information of the image forming operations may represent the types of image forming operations, such as printing, scanning, copying, faxing, e-mail transferring, storing, character recognition, an FTP operation, and web browsing. The setting information necessary for performing the image forming operations may represent, for example, the type of printing paper, the number of printouts, and a printing method.

The interface library 370 may include information about applications executable by the image forming apparatus 300. The UI 360 may provide the user with the applications executable by the image forming apparatus 300 by referring to the interface library 370 and may receive from the user a selection of an application that is to be executed.

The UI 360 may execute the selected application by referring to the interface library 370. For example, the interface library 370 may include location information of execution data for executing an application. The UI 360 may execute the selected application by referring to the interface library 370 and may provide the user with an execution screen or the like of the selected application via a browser.

The interface library 370 may be stored in a non-volatile memory included in the device 350. For example, the interface library 370 may be included in a non-volatile memory, such as a ROM or a flash memory.

The UI 360 may receive from the user a request to perform an image forming operation via the executed application. The UI 360 may receive ID information and setting information of the image forming operation requested to be performed, and may generate the image forming operation by using the received pieces of information.

When the image forming operation is generated, the UI 360 may transmit a request to perform the generated image forming operation to the operation processor 380.

The operation processor 380 performs data conversion and data distribution so that all of image forming operations generated via applications executed by the device 350 may be performed in an appropriate order and at an appropriate speed, and may be implemented within or outside the UI 360.

The operation processor 380 may call an API corresponding to the generated image forming operation, based on the request received from the UI 360 to perform the generated image forming operation. The operation processor 380 may include an API library for the image forming operations performable by the operation performer 320 of the image forming apparatus 300.

For example, when the image forming operation requested to be performed is a scan operation, the operation processor 380 may call a scan API corresponding to the scan operation. The scan API may drive a scan module for performing a scan operation, which is included in the operation performer 320.

At this time, the operation processor 380 may convert a format of the received request to perform an image forming operation into a predetermined data format for calling an API corresponding to the image forming operation. For example, the predetermined data format may be a JSON format, such as Number, String, Boolean, Array, Object, Symbol, null, or undefined.

In other words, with reference to FIG. 3, the operation processor 380 may analyze the received request to perform the image forming operation in order to convert the received request into a request for calling an API corresponding to the image forming operation. In addition, the operation processor 380 may receive data representing a performance result of the image forming operation from the operation performer 320 and may transmit the received data to the UI 360. At this time, the operation processor 380 may convert a format of the data representing the performance result of the image forming operation and transmit the format-changed data.

The operation processor 380 may transmit or receive data to or from the operation performer 320, via a communication interface (not shown) of the device 350 and the communication interface 310 of the image forming apparatus 300. The operation processor 380 may transmit or receive data to or from the operation performer 320 by using an HTTP method.

The operation processor 380 may perform a user authentication required to perform the image forming operation. For example, the operation processor 380 may receive user authentication information obtained by the UI 360 to perform the user authentication. The operation processor 380 may determine whether the received user authentication information is valid, by analyzing user information stored in the image forming apparatus 300 and the received user authentication information. When it is determined that the user authentication information is not valid, the operation processor 380 may terminate connection with the UI 360 and data transmission or reception to or from the UI 360.

The operation processor 380 may manage a connection to the image forming apparatus 300 and settings of the connection. At this time, the operation processor 380 may set a real-time bidirectional connection by using a web socket method, and thus may immediately receive information about an event generated by the image forming apparatus 300.

The image forming apparatus 300 may receive from the device 350 a request to perform an image forming operation and may perform the image forming operation. The communication interface 310 of the image forming apparatus 300 may transmit or receive data to or from external devices. The operation performer 320 of the image forming apparatus 300 may directly perform an image forming operation, and may include a plurality of operation modules that respectively perform various image forming operations. For example, the operation performer 320 may include a print module, a scan module, a copy module, a facsimile module, an e-mail transfer module, a storage module, and a character recognition module.

When the operation performer 320 receives the request to perform an image forming operation from the device 350 via the communication interface 310, the operation performer 320 may perform the image forming operation. In detail, the operation performer 320 may perform the image forming operation by driving a module corresponding to the API called by the operation processor 380 from among the modules included in the operation performer 320.

For example, in response to a request from the user interface unit 360 of the device 350 to perform a print operation, the operation processor 380 may convert the request to perform the print operation to call a print API corresponding to the print operation, and the operation performer 320 may perform the print operation by driving the print module.

FIG. 4 illustrates a UI screen image 400 that is provided by the image forming apparatus 100 of FIG. 1, according to an embodiment of the present disclosure.

Referring to FIG. 4, the image forming apparatus 100 may provide a UI screen including various image forming operations performable by the image forming apparatus 100 and applications executable by the image forming apparatus 100.

The image forming apparatus 100 may provide a method of executing an application, which is a system, by using a UI screen that constitutes an independent single layer (for example, the UI 110 of FIG. 1).

In detail, the image forming apparatus 100 may provide a user with a UI screen, such as, the UI screen image 400 of FIG. 4, by referring to an interface library pre-stored in the UI 110. The interface library may include information about the image forming operations performable by the image forming apparatus 100 and information about the applications executable by the image forming apparatus 100.

For example, the image forming apparatus 100 may provide a print operation performable by the image forming apparatus 100 to the user by referring to the interface library, and, when the user selects the print operation, the image forming apparatus 100 may provide setting information necessary for performing the print operation. The user may generate a print operation by requesting for performance of a print operation via a UI screen and inputting setting information of the print operation.

The image forming apparatus 100 may provide a character recognition application to the user by referring to the interface library, and may execute the character recognition application when the user selects the character recognition application. The image forming apparatus 100 may independently execute the character recognition application by referring to the interface library.

When the image forming operation is generated using the executed application, the image forming apparatus 100 may transmit a request to perform the generated image forming operation to an operation processor that performs operation conversion and data distribution (for example, the operation processor 120 of FIG. 1).

FIG. 5 illustrates a UI screen image 500 that is provided by the image forming apparatus 100 of FIG. 1, according to an embodiment of the present disclosure.

Referring to FIG. 5, the image forming apparatus 100 may provide a UI screen including the UI screen image 500 for executing a print application.

The image forming apparatus 100 may execute the print application selected by a user by referring to the interface library, via the UI (for example, the UI 110 of FIG. 1).

When the print operation is executed, the image forming apparatus 100 may provide pieces of setting information necessary to perform the print operation by referring to the interface library.

For example, the image forming apparatus 100 may provide the user with ID information of image forming apparatuses capable of performing a print operation, and may receive a user input of selecting an image forming apparatus that is to perform an image forming operation.
